Katie Ledecky breaks her own world record to win gold

RIO DE JANEIRO—Nineteen year old Katie Ledecky, from Washington, D. C., swam a 3:56.46 in the 400 free relay in the Olympics today. That rate knocked nearly two seconds off her former world record and secured her first gold medal of the Games today. This was Ledecky’s second medal in two days. On Saturday night, Ledecky earned silver in the women’s 4×100 free relay. Ledecky is set to swim individually in the 200 and 800 frees. It is expected that Ledecky may also anchor the women’s 4×200 free relay.
